Samsung Galaxy S24 Ultra Screen and Battery Assembly Replacement

A fully charged lithium-ion battery can be a safety hazard.

• Drain the battery below 25% if it's at full charge.

If the battery is swollen, take necessary precautions to avoid damage or injury.

Disconnect all cables from your phone.

• Hold down the side key and the volume down button.
• Select "Power off" to turn off your phone.

Avoid overheating the phone's display and internal battery.

• Apply an iOpener to the right edge of the back cover for two minutes, or use a hair dryer, heat gun, or hot plate instead.

Apply a suction handle to the back cover near the right edge.

Use strong, steady force when pulling up on the suction handle — risk of damaging the cover.

• Continue to pull up until a gap forms between the cover and frame.
• If needed, apply more heat following iOpener guidelines to soften adhesive.
• Insert an opening pick into the created gap.

Slide a pick back and forth along the right edge to separate the adhesive.

• Insert the pick near the bottom right corner, leaving it in place to prevent the adhesive from resealing.

Heat the iOpener and apply it to the bottom edge of the back cover for 2 minutes.

• Insert another opening pick beside the first, at the lower right corner.
• Rotate this new opening pick to break apart the adhesive from the corner.

Insert an opening pick at the bottom of the device.

• Guide the pick along the bottom edge to separate the adhesive.
• Leave the pick near the bottom left corner for future reference.

Apply heat to the left edge of the back cover using a iOpener for two minutes.

• Insert a new opening pick beside the existing one, near the left edge.

• Rotate this new pick carefully around the bottom left corner to avoid screen damage.

• The adhesive should start separating as you continue rotating the picks.

Do not exceed 4mm insertion depth to avoid damaging the antenna cable.

• Slide your opening pick along the left edge, stopping before reaching the power button.
• Leave the pick inserted near the power button to prevent resealing.

Apply iOpener to top edge of back cover and heat for 2 minutes.

Insert the opening pick into the gap at the top of the right edge.

• Rotate the opening pick clockwise, working around the top right corner.
• This will help separate the adhesive.

Avoid damaging the sensor or camera with excessive insertion depth.

• Slide the pick along the top edge to separate the adhesive.
• Limit pick insertion to no more than 4 mm to prevent damage.

Slide a pick along the top left corner and down the left edge to separate remaining adhesive.

Avoid inserting the pick more than 4mm to prevent camera damage.

Grab and remove the back cover.

• If the cover is still attached, use an opening pick to separate any resealed adhesive around the edges.
• During reassembly:
• Power on your phone and test all functions before sealing it up.
• Make sure your phone is completely powered down before continuing work.
• Remove any remaining adhesive chunks with a pair of tweezers or your fingers.
• If needed, apply heat to aid in separating the adhesive.

When using custom-cut adhesives, follow this guide.

For double-sided tape, refer to its respective repair guide.

Use a spudger to carefully pry up the wireless charging coil press connector from the motherboard.

Only pry near the arrow mark on the board, avoiding surface-mounted components.

• Disconnect the press connector by prying in the recommended location.
• To reconnect: Align the connector over its socket and press down carefully with one side, then the other, until it clicks into place.

Do not force the connector - if needed, reposition and try again.

Remove the 10 Phillips screws, 4 for the wireless charging coil and 6 for the loudspeaker. Each screw is 3.5 mm long.

Use a spudger to carefully pry up one corner of the wireless charging coil tab on the right edge of the frame.

Insert the opening pick between the tab and the frame.

Insert a SIM eject tool, bit, or straightened paper clip into the SIM card tray hole on the bottom edge of the phone.

• Press the SIM eject tool into the SIM card tray hole to eject the SIM card tray.
• Remove the SIM card tray.

If you accidentally inserted the SIM eject tool into a microphone hole, it's unlikely to have damaged the microphone. Proceed with caution and inspect for any damage.

Remove the daughterboard screws using a Phillips screwdriver.

• The screws are 3.5 mm long and located at the edges of the board.

Do not pry against the battery.

• Use a spudger to pry up the top left corner of the daughterboard, angling it against the frame.
• Remove the daughterboard.

During reassembly, insert the USB-C port at an angle before pressing the daughterboard flat onto the frame.

Use a spudger to gently pry up and release the earpiece speaker press connector.

Remove the earpiece speaker using a Phillips screwdriver.
